SAT/ACT If n is divisible by 2,5, and 14, which of the following is also divisible by these numbers?
A n+7
D n + 20
B n + 10
E n + 70
C n + 14

Option E : n+70 is the correct answer.

Step-by-step explanation:

Given that:

n is divisible by 2,5 and 14.

We have to add a number to n which will make the resulting number also a divisible of 2, 5 and 14.

Therefore,

We will add a number that is multiple of 2,5 and 14

Here,

7 is not a multiple of 2,5 and 14.

20 and 10 are multiples of 2 and 5 but not 14.

70 is a multiple of 2,5 and 14.

14 is a multiple of 2 and 14 but not 5.

Hence,

Option E : n+70 is the correct answer.
